IMPROVEMENT IN APPARATUSFOR SELEQTINQSHQT,

Specification forming part of Letters Patent No. 182,328, dated lSeptemloe1y19, 1876,; application led August 7, 1876. l l

To all whom it may concern:

Be it known that I, ROBERT POOLE, of Baltimorecity, in the1 State of Maryland, have invented certain new and useful Improvements in Apparatus for Selecting Shot, of which the following is a specification Y My invention relates to an apparatus for selecting or separating perfect from imperfect shot.. c

The object of the first part of my invention is to feed the shot in a stream of uniform thickness, from a hopper or receptacle, to separating tablesor shelves; which end I attain by combining, with a hopper, a rotating conveyer or spreader shaft, which Works near to the inclined bottom ot' the hopper ou an axis transverse to the path ofthe shot,intercepts them on their Way to escape from the hopper, and carries the shot both ways from the center, thus distributing `them uniformly over the i ho'pper. i

My invention further consists in constructing a hopper wit-h a slot or opening at the front end, through which the shot escape, a spreading-strip, against which the shot strike before passing through the slot, and aspread erlshat't or distributer, which spreads the shot evenly in the hopper.

The object ofthe next part of myinvention is to adapt the apparatus to themanipulation of 'shot of different sizes and conditions; to which end my invention consists in certain novel constructions and combinations of parts y hereinafter specifically designated.

In the accompanying drawings, which represent all my improvements as embodied in one machine in the best Way now known to me, Figure l represents a plan or top View of so much of the apparatus as is necessary to illustrate the subject-matter herein claimed; and Fig. 2 a vertical central longitudinal section therethrough on the line l l of Fig. l.

A stout frame, A, with inclined side bars B, supports a hopper, G, mounted upon arms Ul, pivoted'a-t b to the frame, so that it may be `adjusted and held in any desired relation to the separating-shelves by suitable Well-known means. The shot to ,be select-ed or assorted are poured into this hopper, and escape through the bottomthereof.l Thev back edgeof the hopper is provided with,aseparating-strip,G2, which may be rendered adjustable by sliding -in grooves in the hopper, or in other well-known screw-threads running in opposite directions from each end of the shaft toward the center thereof, serves still further to distribute the shot uniformlyin the hopper for their escape through its slot. To accommodate 4different sizes of shot the bearings of the shaft are made adjustable in usual wellkuown ways. After escaping from the hopper the shot roll down` a series of separating-shelves, E F G H, in the usual manner, into a trough, I, or other suitable receptacle. During their descent the round or4 perfect shot bound from shelf to shelf, and are deposited in a hopper, while the imperfect or irregular-shaped ones roll ott' to one side, and drop through the spaces between the shelves, as is well understood.

As the shelves are all alike a description of one will be sufficient to show the construction of the others. The shelves areconnected to the side bars by arms c, turning on pivots el, and controlled by set-screws e2 at their rear edges, or that farthest from the hopper, so as to vary their angle of inclination, thus regulating the velocity of the shot.

In selecting or assorting shot of dierent sizes it is necessary to vary the distance between the shelves; but in the shelves heretofore employed, which consist, simply, of plain boards, the adjustment of one shelf necessarily involves the adjustment of the Whole series, as one could not be adjusted .separately Without disturbing its relation to the others. To obviate thi-s objection I construct the shelves with a sliding section,f, controlled by set-screws ff, by which means thewidth of the shelf can be increased or diminished to compensate for the horizontal adjustment, and also to regulate the width of the opening between two adjacent shelves vWithout disturbing the relation of the others, which device, in practice, I have found of great utility.

I claim as my invention-i 1. A shot-distributing hopper, constructed substantiallylas hereinbefore setforth, with an inclined slotted bottom, and a rotating; spreader-shaft, which acts on the shot on their Way vto escape, and distributes them uniformly to the slot.

2. The combination, substantially as hereinbefore set forth, of the slotted hopper, the spreading-shaft, and the spreading-strip.

3. The combination, substantiall y as hereinbefore set forth, of the hopper, the scatteringcone, and the spreader shaft.

4. The series of shot-separating; shelves, constructed substantially as described, each independent of the others, and having their upper ROBERT POOLE.
